[0002] Traditional pig drinking devices mostly use fixed flow valves or simple touch switches, which have problems such as inaccurate water flow regulation and easy contamination of valves. Especially in large-scale farming, they are difficult to meet the drinking needs of pigs at different growth stages. Existing automatic drinkers often rely on electricity or complex sensors, which have high maintenance costs and insufficient reliability. At the same time, the lack of protective design makes the valves easy to be damaged by pig impacts. Therefore, there is an urgent need for an automatic pig drinking water supply device to solve the above problems. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides an embodiment of an automatic water supply device for pigs, comprising a water flow regulating mechanism 1 and a self-service drinking mechanism 2. The water flow regulating mechanism 1 includes a water pipe 3, on which a first ball valve 4 is fixedly installed. A pointer 5 is interference-fitted to the outside of the knob of the first ball valve 4. A fixing plate 6 and a fixing bracket 7 are fixedly installed on the outside of the water pipe 3. An annular plate 8 is fixedly connected to the side of the fixing bracket 7 near the first ball valve 4. Scale lines 9 are evenly distributed on the side of the annular plate 8 away from the fixing bracket 7. When the pointer 5 is vertically upward, the first ball valve 4 is fully open. When the knob of the first ball valve 4 is rotated clockwise, the water flow through the first ball valve 4 decreases. By rotating the knob of the first ball valve 4, the pointer 5 is rotated, and the water flow through the first ball valve 4 can be understood by the scale line 9 pointed to by the pointer 5.

[0022] The self-service drinking water mechanism 2 includes a connecting pipe 10 and a sliding protective cover 17. A second ball valve 11 is fixedly installed on the connecting pipe 10. A connecting rod 12 is fixedly connected to the outer side of the bottom end of the knob of the second ball valve 11. A push-pull rod 19 is rotatably connected to the inner side of the sliding protective cover 17. One end of the connecting pipe 10 is fixedly installed at the bottom end of the water pipe 3. The other end of the connecting pipe 10 is provided with a drinking head 15. An external threaded connector 16 is fixedly connected to the end of the drinking head 15 near the connecting pipe 10. The external threaded connector 16 is threaded onto the connecting pipe 10. A retaining ring 14 is fixedly connected to the side of the connecting pipe 10 near the drinking head 15 of the second ball valve 11. An energy storage spring 13 is nested on the outer side of the connecting pipe 10 near the drinking head 15 of the retaining ring 14. A sliding cover plate 18 is fixedly installed at the end of the sliding protective cover 17. The sliding protective cover 17 and the sliding cover plate 18 are slidably connected to the outer side of the connecting pipe 10.

[0023] The sliding protective cover 17 is slidably connected to the end of the connecting pipe 10 near the drinking head 15, and the end of the sliding protective cover 17 away from the sliding cover plate 18 is tightly attached to the end of the drinking head 15 near the external thread connector 16. The sliding cover plate 18 is slidably connected to the side of the connecting pipe 10 located on the second ball valve 11 away from the retaining ring 14. The sliding protective cover 17 protects the second ball valve 11 and prevents the second ball valve 11 from being impacted.

[0024] One end of the energy storage spring 13 is tightly attached to the retaining ring 14, and the other end of the energy storage spring 13 is tightly attached to the inner end of the sliding protective cover 17. When the pig drinks water, the pig's snout pushes the sliding protective cover 17 to move away from the drinking head 15. The movement of the sliding protective cover 17 compresses the energy storage spring 13 to contract and absorb elastic potential energy. When drinking ends, the pig's snout is removed from the sliding protective cover 17. At this time, the energy storage spring 13 releases elastic potential energy to push the sliding protective cover 17 back to its initial position.

[0025] The end of the push-pull rod 19 away from the sliding protective cover 17 is rotatably connected to the connecting rod 12. The rotatable connection between the two ends of the push-pull rod 19 allows the connecting rod 12 to be pushed and pulled when the push-pull rod 19 moves, thereby driving the knob of the second ball valve 11 to rotate and realize the opening and closing of the valve. The end of the drinking head 15 away from the external thread connector 16 is symmetrically provided with two cut surfaces, which facilitate the installation and removal of the drinking head 15.

[0026] Working principle: During use, the water flow rate is first adjusted according to the growth size of the pigs. The knob of the first ball valve 4 is turned by external force. The rotation of the knob causes the pointer 5 to rotate, and the water flow rate is determined by the scale line 9 indicated by the pointer 5. When the pigs need to drink, they push the sliding protective cover 17 along the connecting pipe 10 away from the drinking head 15 through their snouts. The movement of the sliding protective cover 17 causes the push-pull rod 19 to move. Since the two ends of the push-pull rod 19 are rotatably connected to the inner side of the sliding protective cover 17 and the connecting rod 12 respectively, the movement of the push-pull rod 19 pushes the connecting rod 12. The knob of the second ball valve 11 is turned, and at the same time, the inner side of the sliding protective cover 17 compresses the energy storage spring 13 to contract. The rotation of the knob of the second ball valve 11 opens the valve, and water flows into the drinking head 15 through the connecting pipe 10. At this time, the pig can drink water. When drinking is finished, the pig's mouth leaves the drinking head 15, the energy storage spring 13 loses pressure and rebounds, pushing the sliding protective cover 17 to move closer to the drinking head 15. The movement of the sliding protective cover 17 drives the push-pull rod 19 to move. The movement of the push-pull rod 19 pulls the connecting rod 12, causing the knob of the second ball valve 11 to turn and close the valve, stopping the water supply.
